Comparing Two Independent Population Proportions · Exercise 25

Researchers conducted a study to find out if there is a difference in the use of eReaders by different age groups. Randomly selected participants were divided into two age groups. In the 16- to 29-year-old group, 7% of the 628 surveyed use eReaders, while 11% of the 2,309 participants 30 years old and older use eReaders.

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
